AMD has unleashed its mobile Duron processor - available at clock speeds of 600MHz and 700MHz.

The Mobile AMD Duron processor is the first in a new line of mobile processors that the California-based chip manufacturer plans to introduce in 2001.

The chips are being manufactured in AMD's factory in Austin, Texas. Mobile AMD Duron features 192kb of cache memory and a high-speed 200MHz front side bus, as well as what the company refers to as "enhanced 3D technology."

Also, according to AMD's statement, Japanese PC vendor NEC said it will use the 700MHz variant of the chip in its "LaVie U" series of notebooks.
